DIY Plasterboard Shower: Build a Waterproof Bathroom with Drywall 2026

Our weapon of choice is plasterboard, chosen for its affordability and practicality, since it can be installed with few tools and little time. Even though using plasterboard in a bathroom can raise doubts, manufacturers have developed waterproof boards that resist humid environments for years without warping. As an extra safety measure, treatments with waterproofing liquids and tiling are recommended to ensure durability. For all your home improvement needs, we’ve got you covered.

The Plasterboard Shower Ceiling

The supporting frame for the boards is anchored to the ceiling with a few tie rods that, using spring hooks, allow you to adjust the framework to the desired height. Once the panels are screwed to the frame, apply a self-adhesive mesh tape over the joints to absorb expansions and prevent cracks, then apply joint compound. The joint compound on the joints and screws must be reapplied after about an hour to perfectly level the surface. Any excess can be sanded down.

Frame and Walls of the Plasterboard Shower

The entire ceiling, including the area above the shower, is covered with plasterboard panels. The most difficult part of assembly is lifting the board: if you don’t have helpers, you can use special hooks to hang from the profiles or a T-shaped prop that supports the panel until a few screws are inserted around the perimeter. The shower enclosure wall is built on a 50 mm wide perimeter profile. For durable and stylish bathroom vanities, explore our selection.

Can I tile directly onto plasterboard?
